"As the government of the United States is not in any sense founded on the Christian religion - as it has in itself no character of enmity against the laws, religion or tranquility of Muslims - and, as the said States never entered into any war or act of hostility against any Mahommetan nation, it is declared by the parties that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries."

Article II of the Treaty of Peace and Friendship between the United States of America and the Bey of Tripoli, adopted unanimously by the U.S. Senate in 1797.
